To figure out the answer to this problem, you must first ask yourself this: <span> </span><span>How much is 126 of 700 </span> or <span>What is 126 divded by 700 </span> The answer is 0.18.
So, that means that 0.18 or 18 percent might be your answer.
Now, lets try 18 percent of 700, to see if we get 126.
The maximum number of turning points in a cubic function is 2.
In this case,
The discriminant is , which means the derivative has no real roots. This means there are no critical points and thus no turning points/relative extrema.
